摘要
为开发节水型染整技术,使用非离子型表面活性剂Triton X-100、异辛烷和酸性黑234水溶液制备用于羊毛染色的非离子型反胶束体系,在考察反胶束体系中羊毛对酸性黑234吸附机制的基础上,研究了反胶束和蒸馏水作为介质时染料对羊毛的吸附和染色性能。结果表明,在反胶束中酸性黑234更趋向以单分子态存在,其吸附量随pH值的降低而增加。酸性黑234的吸附反应很好地符合Langmuir等温吸附模型和Lagergren准二级吸附动力学方程。尽管在反胶束中酸性黑234具有相对较低的吸附量,但是其却具有较高的扩散系数和较低的扩散活化能。在反胶束中染色羊毛的颜色特征几乎不发生变化,但是其染色表面深度略低,这可能与染料较高的扩散系数有关。
In order to save water in textile dyeing,the non-ionic reverse micelles were prepared with a non-ionic surfactant Triton X-100 and isooctane by injecting small amount of Acid Black 234 aqueous solution.And then the adsorption and dyeing properties of the dye onto wool in the non-ionic reverse micelle and bulk water were studied,respectively,based on the adsorption mechanism between them examined.The results indicated that Acid Black 234 prefers to exhibit the monomolecular state in the reverse micelle.Low pH values would increase the adsorption amount of the dye onto wool.The adsorption of the dye onto wool showed better agreement with Langmuir isotherm equation and Lagergren second order equation.Acid Black 234 had lower the adsorption amount and diffusion active energy in the reverse micelle than bulk water,but its diffusion coefficient exhibited reverse trend.Little difference in the color characteristics of the dyed wool with Acid Black 234 between in the reverse micelle and bulk water was found.However,a slight decrease in color strength of the dyed wool in the reverse micelle was observed,which may be mainly due to the high diffusion coefficient.
